Improvements should be made to the legacy build documentation to address common user build issues. A couple that have come up recently:

• Users are failing to build due to using a version of a compiler that is too new (the source hasn't been updated to resolve the new build warnings/errors).
• Users are building the driver against a different version of the standard library than the version of the standard library they are building boost against. We should suggest to OS X users to install boost with homebrew instead of building it themselves.
• Users want to add multiple directories to their include path or library path. We should document the syntax for this.
